An implant release mechanism for releasing, for example, a stent (60) is providedwith three restraining wires (62) which pass in the space between a wire guidecatheter (24) and a pusher sheath or dilator (30) and are arranged substantiallyequi-angularly threrearound. Each restraining wire (62) holds both the proximaland distal ends of the stent (60), in this case each holding a proportion of theends of the stent (60). When the restraining wires (62) are pulled they will firstunwrap from the proximal end of the stent (60) and will then release the distalend of the stent (60) so as to allow the stent to become fully deployed within thelumen of the patient. The use of common release wires improves deployment of implantsand reduces the number and volume of components in the device, thereby allowingit to occupy a smaller volume.
